JOHN It. DAVIS, OF BLOOMFIELD, IOWTA.

CO RN-PLANTE R.

To all whom, it 'may concern:

. Be it known that I, JOHN It. DAVIS, of Bloomfield, in the county of Davis and State of Iowa, have invented a new and Improved Gom-Planter; and I do hereby declare the following to be afull and exact description ot" the saine, reference being had to the accompanyingdrawings, making part of this specification, in which Figure l is a plan or top View of my improved corn-planter. Fig. 2 is a vertical loneitudinal section of the same in the line .r '00, Fig. 1. A

Similar letters of reference indicate corresponding partsin the several gures.

The object of this invention is to produce a novel, cheap, and simplified contrivance, whereby the runners ot' a corn-planter may be more readily adjusted to work at any desired depth, raised or lowered at will, and retained in either condition, so as to adapt the machine for operation or for the suspension thereof.

Y The invention consists in the employment of a lever which hasits fulcrum on the main frame, and which is jointed to an arm or secondary lever, which is rigidly secured upon a pivoted frame, to which the runners or furrowshares are attached, the first-mentioned lever being furnished with a spring which operates in connection with a horizontal bar provided with a series of p ins or projections, so as to retain the lever in any position to which it may be turned, as will be hereinafter fully eX- plained.

In order that others skilled in the art to which my invention appertains may be enabled to fully understand and use the same, I

willproceed to describe its construction and operation.

In the accompanying drawings, A may represent various parts of a strong frame, which is mounted upon wheels or drums A and which supports a seat, A2.

may represent the several parts of a frame, which is attached to the frame A by joints or links at a,which permit the frames A B to have their relative positions varied, for the purpose to be hereinafter explained.

G may represent the'furrow-shares or runners, secured respectively to the opposite sides of the frame B, and adapted to move simultaneouslythcrewith.

D represents the draft tongue or pole, supported upon the frame B in the manner shown.

E is a lever or arm, which is' rigidly joined at its front end to the tongue D, and which extends backward in au upwardly-inclined position as far as the frame A, the post BV providing a firm intermediate support. The rear end of the lever E constitutes the point ot' aci tion for a lever, F, which is pivoted to said lever E by links e. The lever F is attached by links f to a small rigid block or post, a',upon the front partof the frame.

j" represents a check or catch secured to the side of the lever F, and which may be retained between the pins or projections g by means of a spring, F', attached to the upper end of the lever F by rivets or otherwise. The pins or projections g are ranged upon an arm, Gr, vwhich is secured to and projects forward from the drivers seat A2.

The operation of the machine will be readily understood from the foregoing description.

When it is desired to raise the runners U vout of contact with the ground, in order to adapt the machine to be more readily turned or entirely suspend the operation, this can be done by merely turning forward the lever F, which the driver, sitting upon his seat A2, can perform with little exertion and without changing the normal position of his body. The 1e- Ver F on being turned forward has its `fulcrum at the rear end of the arm or lever E and its point of action at the front end of the l'rame A, which', being turned up,also elevates the rear end of the frame B, thereby raising the runners ont of contact with the ground.-

It will be seen that when the runners are thus elevated the entire machine is supported by the wheels A A and the neck-yokes, to which the tongueD is attached. To lower the runners to their working position it is'only necessary for the driver to impart a slight lateral movement to the lever F, so as to release the catch f from the pins g, when the natural tendency of the parts will cause them to assume their working position. The red lines in Fig. 2 indicate the relative positions which the two frames A B occupy when the runners are elevated.

It is manifest that the projections g and catch f enable the operator to regulate with facility the depth at which it may be desired E, thelever F, i'ulcrumcrl by the link e to the to Work the runners.
